Pa February 23, ngozi ya moto ku Building 6, Mingshang Xiyuan, Yuhuatai District, Nanjing, inakhudza mitima ya anthu mamiliyoni mazanamazana. Kumayambiriro kwa tsiku la 24, mzinda wa Nanjing unachitika msonkhano wa atolankhani kuti udziwitse za ngozi yamoto ya "2 · 23" m'chigawo cha Yuhuatai, mumzinda wa Nanjing. Lipotilo lidati pofika 24:00 pa 23, anthu 15 adamwalira pa ngozi yamoto, ndipo anthu 44 adalandira chithandizo kuchipatala. Pakati pawo, 1 inali yovuta kwambiri, 1 inali yovuta kwambiri, ndipo 42 anali ovulala pang'ono. Zizindikiro za odwala onse zinali zokhazikika.
Zomwe zidachitika ndi izi. Cha m’ma 4:30 m’maŵa pa February 23, moto unabuka m’gulu la Building 6, Mingshang Xiyuan, Chigawo cha Yuhuatai, mumzinda wa Nanjing. Moto utatha, anthu ozungulira nthawi yomweyo adayimbira apolisi ndipo dipatimenti yoyang'anira zadzidzidzi m'deralo idayankha. Mutalandira uthengawo, yambitsani dongosolo loyankhira mwadzidzidzi. Pambuyo pake, a Nanjing Fire Rescue Detachment adatumiza magalimoto ozimitsa moto opitilira 20 pamalopo kuti akatayidwe. Malinga ndi zomwe boma lidalengeza m'mawa wa pa 23, motowo udazimitsidwa cha m'ma 6 koloko m'mawa womwewo.
Kumayambiriro kwa tsiku la 24, pamsonkhano wa atolankhani womwe unachitikira mumzinda wa Nanjing, Nanjing Fire Rescue Detachment inanena kuti pambuyo pofufuza koyambirira, motowo unayambitsidwa ndi moto m'malo oimika magalimoto a njinga yamagetsi pamtunda wokwera wa nyumba za 6. Kuphatikiza pa kuyimitsidwa kosaloledwa kwa njinga zamagetsi, kukana kwa moto kwa zida zotchingira zomangira makoma akunja kumagwirizananso kwambiri ndi kufalikira kwa moto.
Ndi bwino kuyika zinthu zotetezera kutentha pakhoma lakunja la nyumba. Zingathe kusunga kutentha nthawi yozizira komanso kuteteza kutentha nthawi yachilimwe, koma chitetezo cha moto sichinganyalanyazidwe. Zinthu zotetezera kutentha zomwe zilipo pano zimagawidwa m'magulu anayi: Gulu A (losayaka), Gulu B1 (loyaka), Gulu B2 (loyaka) ndi Gulu B3 (loyaka). "Malamulo a Kapangidwe ka Nyumba Zoteteza Moto" m'dziko lathu ali ndi zofunikira kwambiri pakugwiritsa ntchito zipangizo. Ndiye kodi zinthu zotetezera kutentha zomwe zimagwiritsidwa ntchito kwambiri ndi ziti?
- Polystyrene board: Ili ndi ntchito yabwino yotchinjiriza kutentha, mtengo wotsika, komanso zomangamanga zosavuta komanso zosavuta. Zoipa: Kulephera kukana moto, nthawi zambiri B2. Ngozi zingapo zamoto ku China zimagwirizana ndi kukana kwamoto kwakunja kwa zida zotchingira khoma.
- Bolodi la ubweya wa miyala: Chopangira chachikulu ndi thanthwe lachilengedwe, choncho chimakhala ndi kutentha kwambiri. Thermal conductivity ndi yotsika kwambiri ndipo imakhala ndi zinthu zabwino zotetezera kutentha. Choyipa chake ndi chakuti mphamvu yotsika yapansi imapangitsa kuti malo okongoletsera akhale osagwirizana, omwe amawonekera makamaka padzuwa. Panthawi imodzimodziyo, matabwa a rock wool sakonda kwambiri ogwira ntchito yomanga, ndipo ulusi wa rock wool umapangitsa khungu kuyabwa. Kulemera kwakukulu kwa matabwa a ubweya wa miyala ndi njira zomangira zopanda pake zingathe kupangitsa kuti khoma lotsekera kunja ligwe, zomwe zimapangitsa ngozi zachitetezo.
- Chithovu cha Melamine: Chithovu cha melamine chimapangidwa ndi melamine yopangidwa ndi thovu la microwave. Melamine palokha ndi zinthu zomwe zimawotcha moto zomwe zimakhala ndi nayitrogeni mpaka 70%. Chifukwa chake, thovu la melamine limatha kukwaniritsa zinthu zabwino kwambiri zoletsa moto popanda kuwonjezera zoletsa zamoto. Kumwamba kumangoyamba kuyaka pamene kukhudzana ndi lawi lotseguka. Zimawonongeka mwamsanga pambuyo poyaka moto kuti zipange mpweya wambiri wosayaka, wosayaka, nayitrogeni, womwe umalekanitsa mpweya ndikuchepetsa kutentha. Nthawi yomweyo, wosanjikiza wandiweyani wa coke umapangidwa mwachangu pamwamba pa thupi loyaka moto kuti uteteze bwino kuti kuyaka kupangike mpaka kuzigawo zakuya. Lawi lotseguka lizimitsidwa pokhapokha litachoka, ndiko kuti, lizimitsidwa pambuyo posiya moto.
Popanda kuwonjezera zoletsa moto, thovu la melamine limatha kukumana ndi B1 low flammability mulingo wotchulidwa ku Germany's DIN4102 ndi American Insurance Institute's UL 94-V-0 high flame retardant material standard, ndipo yadutsa EU BS6853 ndi NFF16-101 , DIN5510 ndi chitetezo cha dziko langa, komanso chitetezo cha dziko langa. GBIT8624-2006 B1 mlingo retardant lawi muyezo.
Thovu la Melamine ndi dongosolo la kapangidwe ka latisi la magawo atatu lomwe lili ndi mipata yokwanira, chiŵerengero cha kutalika mpaka m'mimba mwake (L/D) cha latisi yake chili pakati pa 10-20, ndipo kuchuluka kwa thovu la melamine la 8.5KG/M3 kuli ndi chiŵerengero chachikulu cha maselo otseguka choposa 99%. Kapangidwe ka gridi kakang'ono ka magawo atatu kamapangitsa kuti kutentha kwa mpweya kusamayende bwino, kuphatikiza ndi kukhazikika kwapadera kwa kutentha kochepa, kotero kuti kumakhala ndi kutchinjiriza kwabwino kwa kutentha komanso mphamvu yosungira kutentha (kutulutsa kutentha, 0.035 W / (m * K))), kumakhala kovuta kusintha zinthu zotchinjiriza kutentha zopepuka.
Ponseponse, thovu la melamine ndiye njira yabwino kwambiri yotsekera khoma lakunja.
Kwa mayunitsi omanga ndi oyang'anira, kuchita izi zitha kuteteza moto:
- Tsatirani mosamalitsa udindo woyang'anira chitetezo cha moto m'magawo omanga ndi mayunitsi omanga, ndikumveketsa bwino ntchito zowongolera moto ndi oyang'anira. Zida zotetezera moto za nyumba zomwe zagwiritsidwa ntchito ziyenera kusamalidwa bwino.
- Ndizoletsedwa kugwiritsa ntchito zinthu zoyaka komanso zoyaka ngati zida zakunja zotchingira kunja kwa makoma akunja a nyumba zapamwamba za anthu. Kwa nyumba zachitukuko zomwe zimagwiritsa ntchito zida zotsekereza zakunja zotchingira moto kapena kugwiritsa ntchito zida zakunja zakunja zokhala ndi zibowo pakati pa khoma loyambira ndi wosanjikiza wokongoletsa, ndizoletsedwa kugwiritsa ntchito moto kapena magetsi pamakoma awo akunja.
- Kwa nyumba zapamwamba zachitukuko zomwe zili ndi machitidwe otetezera khoma lakunja, bungwe loyang'anira lidzakhazikitsa zikumbutso ndi zizindikiro zochenjeza pakhomo lalikulu ndi malo ozungulira okhudzidwa kuti asonyeze ntchito yoyaka moto ndi zofunikira zotetezera moto pazitsulo zakunja zakunja.
- Ngati njira yotsekera kunja kwa khoma lakunja kwa nyumba yachibadwidwe chapamwamba ikuwonongeka, kusweka kapena kugwa, iyenera kukonzedwa panthawi yake. Pomanga kunja kwa khoma lotchingira khoma la nyumba zokwezeka kwambiri, gulu lomangali liyenera kuchitapo kanthu pofuna kupewa kudzipatula kwa moto ndikuletsa okhalamo ndikugwiritsa ntchito kuonetsetsa chitetezo cha ogwira ntchito mnyumbamo.
- Ndizoletsedwa kwambiri kukhazikitsa zikwangwani, mabokosi opepuka ndi zida zina zamagetsi zotentha kwambiri pamakoma akunja achitetezo opangidwa ndi zinthu zoyaka komanso zoyaka. Ndizoletsedwa kuti muwunjike zinthu zoyaka ndi zoyaka mozungulira nyumbayo, komanso zoletsedwa kukhazikitsa milu yamagetsi yamagetsi pafupi ndi nyumbayo.
